On chateau 5g there are two wifi software interfaces, one for 2.4Ghz and one for 5Ghz. It seems possible to configure one in station mode and the other one in ap-bridge mode. The use-case would be to connect to a public wifi using an external antenna on the roof of a vehicle and serve wifi clients inside the vehicle using the other interface, possibly with internal antennas.
I see on https://confusedbird.com/thread-119.html that there are two wifi antenna ports, not sure if one is for 2.4Ghz and one for 5Ghz or if they are shared and used for diversity?
Is that configuration a valid one?
